 * getResources
 *
 * A general purpose Resource listing and summarization snippet for MODX 2.x.

 *
 * TEMPLATES
 *
 * tpl - Name of a chunk serving as a resource template
 * [NOTE: if not provided, properties are dumped to output for each resource]
 *
 * tplOdd - (Opt) Name of a chunk serving as resource template for resources with an odd idx value
 * (see idx property)
 * tplFirst - (Opt) Name of a chunk serving as resource template for the first resource (see first
 * property)
 * tplLast - (Opt) Name of a chunk serving as resource template for the last resource (see last
 * property)
 * tpl_{n} - (Opt) Name of a chunk serving as resource template for the nth resource
 *
 * tplCondition - (Opt) Defines a field of the resource to evaluate against keys defined in the
 * conditionalTpls property. Must be a resource field; does not work with Template Variables.
 * conditionalTpls - (Opt) A JSON object defining a map of field values and the associated tpl to
 * use when the field defined by tplCondition matches the value. [NOTE: tplOdd, tplFirst, tplLast,
 * and tpl_{n} will take precedence over any defined conditionalTpls]
 *
 * tplWrapper - (Opt) Name of a chunk serving as a wrapper template for the output
 * [NOTE: Does not work with toSeparatePlaceholders]
 *
 * SELECTION
 *
 * parents - Comma-delimited list of ids serving as parents
 *
 * context - (Opt) Comma-delimited list of context keys to limit results by; if empty, contexts for all specified
 * parents will be used (all contexts if 0 is specified) [default=]
 *
 * depth - (Opt) Integer value indicating depth to search for resources from each parent [default=10]
 *
 * tvFilters - (Opt) Delimited-list of TemplateVar values to filter resources by. Supports two
 * delimiters and two value search formats. The first delimiter || represents a logical OR and the
 * primary grouping mechanism.  Within each group you can provide a comma-delimited list of values.
 * These values can be either tied to a specific TemplateVar by name, e.g. myTV==value, or just the
 * value, indicating you are searching for the value in any TemplateVar tied to the Resource. An
 * example would be &tvFilters=`filter2==one,filter1==bar%||filter1==foo`
 * [NOTE: filtering by values uses a LIKE query and % is considered a wildcard.]
 * [NOTE: this only looks at the raw value set for specific Resource, i. e. there must be a value
 * specifically set for the Resource and it is not evaluated.]
 *
 * tvFiltersAndDelimiter - (Opt) Custom delimiter for logical AND, default ',', in case you want to
 * match a literal comma in the tvFilters. E.g. &tvFiltersAndDelimiter=`&&`
 * &tvFilters=`filter1==foo,bar&&filter2==baz` [default=,]
 *
 * tvFiltersOrDelimiter - (Opt) Custom delimiter for logical OR, default '||', in case you want to
 * match a literal '||' in the tvFilters. E.g. &tvFiltersOrDelimiter=`|OR|`
 * &tvFilters=`filter1==foo||bar|OR|filter2==baz` [default=||]
 *
 * where - (Opt) A JSON expression of criteria to build any additional where clauses from. An example would be
 * &where=`{{"alias:LIKE":"foo%", "OR:alias:LIKE":"%bar"},{"OR:pagetitle:=":"foobar", "AND:description:=":"raboof"}}`
 *
 * sortby - (Opt) Field to sort by or a JSON array, e.g. {"publishedon":"ASC","createdon":"DESC"} [default=publishedon]
 * sortbyTV - (opt) A Template Variable name to sort by (if supplied, this precedes the sortby value) [default=]
 * sortbyTVType - (Opt) A data type to CAST a TV Value to in order to sort on it properly [default=string]
 * sortbyAlias - (Opt) Query alias for sortby field [default=]
 * sortbyEscaped - (Opt) Escapes the field name(s) specified in sortby [default=0]
 * sortdir - (Opt) Order which to sort by [default=DESC]
 * sortdirTV - (Opt) Order which to sort by a TV [default=DESC]
 * limit - (Opt) Limits the number of resources returned [default=5]
 * offset - (Opt) An offset of resources returned by the criteria to skip [default=0]
 * dbCacheFlag - (Opt) Controls caching of db queries; 0|false = do not cache result set; 1 = cache result set
 * according to cache settings, any other integer value = number of seconds to cache result set [default=0]
 *
 * OPTIONS
 *
 * includeContent - (Opt) Indicates if the content of each resource should be returned in the
 * results [default=0]
 * includeTVs - (Opt) Indicates if TemplateVar values should be included in the properties available
 * to each resource template [default=0]
 * includeTVList - (Opt) Limits the TemplateVars that are included if includeTVs is true to those specified
 * by name in a comma-delimited list [default=]
 * prepareTVs - (Opt) Prepares media-source dependent TemplateVar values [default=1]
 * prepareTVList - (Opt) Limits the TVs that are prepared to those specified by name in a comma-delimited
 * list [default=]
 * processTVs - (Opt) Indicates if TemplateVar values should be rendered as they would on the
 * resource being summarized [default=0]
 * processTVList - (opt) Limits the TemplateVars that are processed if included to those specified
 * by name in a comma-delimited list [default=]
 * tvPrefix - (Opt) The prefix for TemplateVar properties [default=tv.]
 * idx - (Opt) You can define the starting idx of the resources, which is an property that is
 * incremented as each resource is rendered [default=1]
 * first - (Opt) Define the idx which represents the first resource (see tplFirst) [default=1]
 * last - (Opt) Define the idx which represents the last resource (see tplLast) [default=# of
 * resources being summarized + first - 1]
 * outputSeparator - (Opt) An optional string to separate each tpl instance [default="\n"]
 * wrapIfEmpty - (Opt) Indicates if the tplWrapper should be applied if the output is empty [default=0]
