ExpressionParserToNumericString Method

Convert a supposedly numeric string into a validated numeric string. This method has two purposes:

1. Convert likely non-numerics to valid numerics. In particular, null/empty string to zero, "false" to zero, "true" to one.
2. Protect against possible SQL injection attack by converting supposedly numeric values that don't parse to zero.

In the case of an unexpected, non-parsable value, a simple SQL injection attack detection is performed and a devlog and request log entry generated if a SQL injection attempt looks likely. This class is deprecated. Use NetQuarry.ExpressionParser.ToNumericString.
