Transforms string letter case to camel, snake, dash and underscore without activesupport dependencies.  
Forked from [Rails API CaseTransform gem](https://github.com/rails-api/case_transform)

## Why

We want a simple string method without polluting String class and lightweight.  
If you want to use this into Rails application or any Ruby application with activesupport dependencies, 
you might want to consider [the original one instead.](https://github.com/rails-api/case_transform)

## Install

```ruby
gem 'case_transform2'
```

or

```bash
gem install case_transform2
```

## Warning

if you use 0.x version and want to upgrade to newest version
you *must* rename all CaseTransform to be CaseTransform2

## Usage

```ruby
require 'case_transform2'

value = "hello_world"
CaseTransform2.camel_lower(value) # => helloWorld

value = "hello_world"
CaseTransform2.camel(value) # => HelloWorld

value = "hello_world"
CaseTransform2.dash(value) # => hello-world

value = "helloWorld"
CaseTransform2.underscore(value) # => hello_world
```

`value` can be any of Array, Hash, Symbol, or String.
Any other object type will just be returned.

## Transforms
