/*
Package toml provides facilities for decoding and encoding TOML configuration
files via reflection. There is also support for delaying decoding with
the Primitive type, and querying the set of keys in a TOML document with the
MetaData type.
Package toml implements decoding and encoding of TOML files.
The specification implemented: https://github.com/toml-lang/toml
This package supports TOML v1.0.0, as listed on https://toml.io
The sub-command github.com/BurntSushi/toml/cmd/tomlv can be used to verify
whether a file is a valid TOML document. It can also be used to print the
type of each key in a TOML document.
There is also support for delaying decoding with the Primitive type, and
querying the set of keys in a TOML document with the MetaData type.
Testing
There are two important types of tests used for this package. The first is
contained inside '*_test.go' files and uses the standard Go unit testing
framework. These tests are primarily devoted to holistically testing the
decoder and encoder.
The second type of testing is used to verify the implementation's adherence
to the TOML specification. These tests have been factored into their own
project: https://github.com/BurntSushi/toml-test
The reason the tests are in a separate project is so that they can be used by
any implementation of TOML. Namely, it is language agnostic.
The github.com/BurntSushi/toml/cmd/tomlv package implements a TOML validator,
and can be used to verify if TOML document is valid. It can also be used to
print the type of each key.

## v1.1
### Added
- Cookies can be added to the HTTP request, either via the `Cookies` map or the `Cookie()` function
- Function `GetWithClient()` provides the ability to send the request with a custom HTTP client
- Function `FindStrict()` finds the first instance of the mentioned tag with the exact matching values of the provided attribute (previously `Find()`)
- Function `FindAllStrict()` finds all the instances of the mentioned tag with the exact matching values of the attributes (previously `FindAll()`)
## Changed
- Function `Find()` now finds the first instance of the mentioned tag with any matching values of the provided attribute.
- Function `FindAll()` now finds all the instances of the mentioned tag with any matching values of the provided attribute.
