kotlin extension to pluralize and singularize strings

Pluralization:

"person".pluralize()        # => "people"
"post".pluralize()          # => "posts"
"sheep".pluralize()         # => "sheep"
"foot".pluralize()          # => "feet"

Singularization:

"words".singularize()       # => "word"
"octopi".singularize()      # => "octopus"
"people".singularize()      # => "person"
"feet".singularize()        # => "foot"

Quantities:

"person".pluralize(1)       # => "person"
"person".pluralize(2)       # => "people"

repositories {
    jcenter()
    maven { url "https://jitpack.io" }
 }
 dependencies {
    compile 'com.github.cesarferreira:kotlin-pluralizer:1.0.0'
 }

I welcome and encourage all pull requests. It usually will take me within 24-48 hours to respond to any issue or request. Here are some basic rules to follow to ensure timely addition of your request:

1. Match coding style (braces, spacing, etc.) This is best achieved using CMD+Option+L (Reformat code) on Mac (not sure for Windows) with Android Studio defaults.
2. If its a feature, bugfix, or anything please only change code to what you specify.
3. Please keep PR titles easy to read and descriptive of changes, this will make them easier to merge :)
4. Pull requests must be made against develop branch. Any other branch (unless specified by the maintainers) will get rejected.
5. Check for existing issues first, before filing an issue.
6. Have fun!
