> This is a simple helper to extract values from a string based on a pattern.

A Ruby port of [laktek's](https://github.com/laktek/) [extract-values](https://github.com/laktek/extract-values).

## Installation

    gem 'excise'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install excise

## Usage

```ruby
require 'excise'

# Basic use
Excise('About {result_count} results ({load_time} seconds)',
       'About 49,000,000 results (0.15 seconds)')
#=> {:result_count=>"49,000,000", :load_time=>"0.15"}

# Memoize pattern for performance improvement
