-Easy and safe casting from one type to another in Go
-
-Don’t Panic! ... Cast
-
-## What is Cast?
-
-Cast is a library to convert between different go types in a consistent and easy way.
-
-Cast provides simple functions to easily convert a number to a string, an
-interface into a bool, etc. Cast does this intelligently when an obvious
-conversion is possible. It doesn’t make any attempts to guess what you meant,
-for example you can only convert a string to an int when it is a string
-representation of an int such as “8”. Cast was developed for use in
-[Hugo](https://gohugo.io), a website engine which uses YAML, TOML or JSON
-for meta data.
-
-## Why use Cast?
-
-When working with dynamic data in Go you often need to cast or convert the data
-from one type into another. Cast goes beyond just using type assertion (though
-it uses that when possible) to provide a very straightforward and convenient
-library.
-
-If you are working with interfaces to handle things like dynamic content
-you’ll need an easy way to convert an interface into a given type. This
-is the library for you.
-
-If you are taking in data from YAML, TOML or JSON or other formats which lack
-full types, then Cast is the library for you.
-
-## Usage
-
-Cast provides a handful of To_____ methods. These methods will always return
-the desired type. **If input is provided that will not convert to that type, the
-0 or nil value for that type will be returned**.
-
-Cast also provides identical methods To_____E. These return the same result as
-the To_____ methods, plus an additional error which tells you if it successfully
-converted. Using these methods you can tell the difference between when the
-input matched the zero value or when the conversion failed and the zero value
-was returned.
-
-The following examples are merely a sample of what is available. Please review
-the code for a complete set.
-
-### Example ‘ToString’:
-
-    cast.ToString("mayonegg")         // "mayonegg"
-    cast.ToString(8)                  // "8"
-    cast.ToString(8.31)               // "8.31"
-    cast.ToString([]byte("one time")) // "one time"
-    cast.ToString(nil)                // ""
-
-	var foo interface{} = "one more time"
-    cast.ToString(foo)                // "one more time"
-
-
-### Example ‘ToInt’:
-
-    cast.ToInt(8)                  // 8
-    cast.ToInt(8.31)               // 8
-    cast.ToInt("8")                // 8
-    cast.ToInt(true)               // 1
-    cast.ToInt(false)              // 0
-
-	var eight interface{} = 8
-    cast.ToInt(eight)              // 8
-    cast.ToInt(nil)                // 0
