This plugin gives you the ability to use the Dynatrace instrumentation in your hybrid application (Cordova, Ionic, ..). It uses the Mobile Agent, the JavaScript Agent and the Javascript Bridge. The Mobile Agent will give you all device specific values con

## Caseless -- wrap an object to set and get property with caseless semantics but also preserve caseing.

This library is incredibly useful when working with HTTP headers. It allows you to get/set/check for headers in a caseless manner while also preserving the caseing of headers the first time they are set.

## Usage

```javascript
var headers = {}
  , c = caseless(headers)
  ;
c.set('a-Header', 'asdf')
c.get('a-header') === 'asdf'
```

## has(key)

Has takes a name and if it finds a matching header will return that header name with the preserved caseing it was set with.

```javascript
c.has('a-header') === 'a-Header'
```

## set(key, value[, clobber=true])

Set is fairly straight forward except that if the header exists and clobber is disabled it will add `','+value` to the existing header.

```javascript
c.set('a-Header', 'fdas')
c.set('a-HEADER', 'more', false)
c.get('a-header') === 'fdsa,more'
```

## swap(key)

Swaps the casing of a header with the new one that is passed in.

```javascript
var headers = {}
  , c = caseless(headers)
  ;
c.set('a-Header', 'fdas')
c.swap('a-HEADER')
c.has('a-header') === 'a-HEADER'
headers === {'a-HEADER': 'fdas'}
```
