* Fixed misspell
* Fixed ineffassign
`user` and `password` always got overwritten
`orderedVals` was initialized with an empty array but always got overwritten by either `sortByLines()` or `sortAlphabetical`
`err` was assigned a `nil` value that was either overwritten or unused anyways
* Fix comment for DeletePath
The comment assumed the method was named Delete, i guess a rename happened at some point
* Update doc_test.go
Move all the query system to its own package. The reason is to
avoid it to rely on unexported methods and structures, and move
it out of the main package since this is really not a core
feature. It is still tied to the toml.TomlTree and toml.Position
structures for now.
* Move query mechanism to its own subpackage
* Rename QueryResult to Result to avoid stutter
* Add query.CompileAndExecute
Fixes#116
