\qmltype CurrencyAmountInput
\inherits StatusTextField
\brief Provides a text input field that accepts a numeric value, with optional (currency) symbol (defaults to "USD").
Utilizes a builtin DoubleValidator to validate the user's input.
It accepts both the native decimal separator and optionally a period (`.`) for locales that don't use this.
\inqmlmodule shared.controls 1.0
Internally it uses FormattedDoubleProperty object that keeps track of the value.
