## ToString (//flowstdlib/fmt/to_string)
Convert an input type to a String
Current types supported are:
* null - A null will be printed as "null"
* boolean - boolean JSON value
* number - A JSON Number
* string - a bit redundant, but it works
* array - An JSON array of values that can be converted, they are converted one by one
* object - a Map of names/objects that will also be printed out
### Include using
```toml
[[process]]
source = "lib://flowstdlib/fmt/to_string"
```
