KeepIf[ <Condition>, <List> ]
Creates a new list that only contains those elements of the initial list that fulfil the condition.
Example: KeepIf[x<3, {1, 2, 3, 4, 1, 5, 6}] returns the new list {1, 2, 1}.
Note: For list of numbers arbitrary condition may be used. For list of other objects one can use only conditions of the form x==constant or x!=constant.
