Deletes all instances of a given element from an array, substring from a

string, or key from a hash.

*Examples:*
|

delete(['a','b','c','b'], 'b')

Would return: ['a','c']

delete({'a'=>1,'b'=>2,'c'=>3}, 'b')

Would return: {'a'=>1,'c'=>3}

delete({'a'=>1,'b'=>2,'c'=>3}, ['b','c'])

Would return: {'a'=>1}

delete('abracadabra', 'bra')
