Given a region of code within a statement, replaces all occurrences of
that code with a temporary variable. Declares and initializes the
temporary variable right above the statement that included the
selected expression.

Constructor. Generally shouldn't be called with any arguments.

.PD
Accepts either a \f(CW\*(C`PPI::Document\*(C'\fR to process or a string containing
the code (which will be converted into a \f(CW\*(C`PPI::Document\*(C'\fR) to process.
.Sp
Given the region of code specified by start_location and end_location,
replaces that code with a temporary variable with the name given
in varname (defaults to \f(CW\*(C`tmp\*(C'\fR). Declares and initializes
the temporary variable right above the statement that included the
selected expression.
.Sp
Returns a \f(CW\*(C`PPIx::EditorTools::ReturnObject\*(C'\fR with the modified code
as a string available via the \f(CW\*(C`code\*(C'\fR accessor (or as a \f(CW\*(C`PPI::Document\*(C'\fR
via the \f(CW\*(C`ppi\*(C'\fR accessor), and the \f(CW\*(C`PPI::Token\*(C'\fR where the new variable
is declared available via the \f(CW\*(C`element\*(C'\fR accessor.
.Sp
Croaks with a \*(L"no token\*(R" exception if no token is found at the location.
Croaks with a \*(L"no statement\*(R" exception if unable to find the statement.
