[Solved] Multiple Instances of Snippets in MODx Revolution

<?php
# csv2table 0.1 - Converts CSV to HTML table
# Created by Chris Pratt 09/08/09.
# -----------------------------------------------------
# _Version_History_
# 0.1 - Inital Release
# 
# _Basic_Usage_
# This snippet will only return the content of the table and not the
# opening and closing <table> tags. This is by design to allow you to
# add any attributes, classes or id to the table at will.
#
# Ex.
#
#   <table>
#     [[csv2table? &csv=`/path/to/file.csv`]]
#   </table>
#
# _Parameters_
# &csv           : Path to CSV file (relative to document root)
# &delimiter     : Character that separates values (defaults to `,`)
# &enclosure     : Character that encloses strings (defaults to `"`)
# &hasColHeader  : First row is column headings (boolean 0 or 1, defaults to 1)
# &hasRowHeader  : First column of each row is a header (boolean 0 or 1, defaults to 0)
# &alternateRows : Add a class to every 2nd row (boolean 0 or 1, defaults to 1)
# &altRowClass   : Classname to use for alternating rows (defaults to `alt`)
#
# _Notes_
# MODx snippets can be called with either `[[...]]` or `[!...!]`. The first
# is a "cached" snippet call: the results of the snippet will be saved and
# used again later instead of re-running the snippet. The second form is an
# "uncached" snippet call: the results will not be saved and the snippet will
# be run each time. Processing CSV files, especially large CSV files, may
# consume an inordinant amount of resources, so you should always used the
# "cached" version (`[[...]]`) of the snippet call to save processing time.
