Adding unwrap and unwrapFull methods to StringUtils
Adding the following methods from `StringUtils`:
* `public static String unwrap(String str, char unwrapChar)`
* `public static String unwrapFull(String str, char unwrapChar)`
* `public static String unwrap(String str, String unwrapStr)`
* `public static String unwrapFull(String str, String unwrapStr)`
* `public static String unwrap(String str, String unwrapLeft, String
unwrapRight)`
* `public static String unwrapFull(String str, String unwrapLeft, String
unwrapRight)`
These methods unwraps (fully or not) the string parameter
Usage:
```
// public static String unwrap(String str, char unwrapChar)
StringUtils.unwrap("", '\0') = ""
StringUtils.unwrap("xabx", 'x') = "ab"
StringUtils.unwrap("\"ab\"", '\"') = "ab"
StringUtils.unwrap("\"\"ab\"\"", '\"') = "\"ab\""
StringUtils.unwrap("'ab'", '\'') = "ab"
StringUtils.unwrap("''ab''", '\'') = "'ab'"
StringUtils.unwrap("'''ab'''", '\'') = "''ab''"
StringUtils.unwrap("'\"abcd\"'", '\'') = "\"abcd\""
StringUtils.unwrap("'\"abcd\"'", '\"') = "'\"abcd\"'"
// public static String unwrapFull(String str, char unwrapChar)
StringUtils.unwrapFull("", '\0') = ""
StringUtils.unwrapFull("xabx", 'x') = "ab"
StringUtils.unwrapFull("xxxxxxabxxxxxx", 'x') = "ab"
StringUtils.unwrapFull("\"ab\"", '\"') = "ab"
StringUtils.unwrapFull("\"\"ab\"\"", '\"') = "ab"
StringUtils.unwrapFull("'ab'", '\'') = "ab"
StringUtils.unwrapFull("'x'ab'x'", '\'') = "x'ab'x"
StringUtils.unwrapFull("''ab''", '\'') = "ab"
StringUtils.unwrapFull("'''''ab'''''", '\'') = "ab"
StringUtils.unwrapFull("''''x'ab'''''", '\'') = "x'ab'"
StringUtils.unwrapFull("'ab''''", '\'') = "ab'''"
// public static String unwrap(String str, String unwrapStr)
StringUtils.unwrap("xxabxx", "xx") = "ab"
StringUtils.unwrap("xxxxabxxxx", "xx") = "xxabxx"
StringUtils.unwrap("xx xxabxx xx", "xx") = " xxabxx "
