FunK, the missing kotlin functions

This small library adds those functions to Kotlin that you are surpised that didn't exist in the first place.

compile 'com.tonylawrence:funk:1.2.2'

<dependency>
    <groupId>com.tonylawrence</groupId>
    <artifactId>funk</artifactId>
    <version>1.2.2</version>
</dependency>

It is now possible to compose two functions together (assuming that the output / input matches)

f compose g == g ° f

We can now convert types into optional (nullable) values instead of throwing exception

"10".toIntOption = 10

"foo".toIntOption = null
