New feature: Conditionals

[ashwin100196]

This feature would allow adding conditions on the DataFrame and then assigning value for a new column

Example

A > 5 & B < 10; Create Flag as 1, else Flag as 0

This could then be used to create masks on the data to be used by the already present Filter block. (for future enhancements)

I like this idea. I think it opens a discussion about merging/joining/masking. Does it make sense for a single node type to join two streams of data or are these actions all distinct enough to have their own nodes?
