Strip
This function Strips characters from string
Usage:
{{#invoke:String2|strip|source_string|characters_to_strip|plain_flag}}
Parameters
source: The string to strip
chars:  The pattern or list of characters to strip from string, replaced with ''
plain:  A flag indicating that the chars should be understood as plain text. defaults to true.
Leading and trailing whitespace is also automatically stripped from the string.

--[[
Match any
Returns the index of the first given pattern to match the input. Patterns must be consecutively numbered.
Returns the empty string if nothing matches for use in {{#if:}}
Usage:
{{#invoke:String2|matchAll|source=123 abc|456|abc}} returns '2'.
Parameters:
source: the string to search
plain:  A flag indicating that the patterns should be understood as plain text. defaults to true.
1, 2, 3, ...: the patterns to search for
