contains, ContainsCase

Purpose: Looks whether a substring is contained in a string.

The ContainsCase() function works very similar but is not case sensitive.

Return Values: Returns true if and only if string contains the substring.

Example 1:

input:	resulting output:
<? contains("Hello World","ello")>	true
<? contains("Hello World","xello")>	false

Example 2:

input:	resulting output:
<if contains("Helmut is a Wizard","Wiz") > Helmut is a Wiz. < else > Helmut should use heitml. <\p> Then he'd be a programming Wiz like Keith. < /if>	Helmut is a Wiz.
