/**
@file mp_searchcols.sas
@brief Searches all columns in a library
@details
Scans a set of libraries and creates a dataset containing all source tables
containing one or more of a particular set of columns
Usage:
%mp_searchcols(libs=sashelp work, cols=name sex age)
@param libs= (SASHELP) Space separated list of libraries to search for columns
@param cols= Space separated list of column names to search for (not case
sensitive)
@param outds= (mp_searchcols) the table to create with the results. Will have
one line per table match.
@param match= (ANY) The match type. Valid values:
@li ANY - The table contains at least one of the columns
@li WILD - The table contains a column with a name that partially matches
@version 9.2
