Function equals( s1, s2 )

Description:
Determines whether two strings are equal.

This will usually give the same result as s1==s2, but it is arguably safer and may behave better when comparing different kinds of blank strings.

Parameters:
s1 (String)
first string
s2 (String)
second string
Return Value (boolean):
true if s1 and s2 are both blank, or have the same content
Signature:
boolean equals(String, String)
