Functionality related to combing Leiningen dependency sequences for license
information.

The core matching functionality within lice-comb. Matching is provided for
three categories of input, and uses a different process for each:

1. License names
2. License uris
3. License texts

Each matching fn has two variants:

1. A 'simple' version that returns a set of SPDX expressions (`String`s)
2. An 'info' version that returns an 'expressions-info map' containing
   metadata on how the determination was made (including confidence
   information)

An expressions-info map has this structure:

* key:   an SPDX expression (`String`)
* value: a sequence of 'expression-info' maps

An expression-info map has this structure:

* `:id` (`String`, optional):
  The portion of the SPDX expression that this info map refers to (usually,
  though not always, a single SPDX identifier).
* `:type` (either `:declared` or `:concluded`, mandatory):
  Whether this identifier was unambiguously declared within the input or was
  instead concluded by lice-comb (see [the SPDX FAQ](https://wiki.spdx.org/view/SPDX_FAQ)
  for more detail on the definition of these two terms).
* `:confidence` (one of: `:high`, `:medium`, `:low`, only provided when
  `:type` = `:concluded`):
  Indicates the approximate confidence lice-comb has in its conclusions for
  this particular SPDX identifier.
* `:confidence-explanations` (a set of keywords, optional):
  Describes why the associated `:confidence` was not `:high`.
* `:strategy` (a keyword, mandatory):
  The strategy lice-comb used to determine this particular SPDX identifier.
  See [[lice-comb.utils/strategy->string]] for an up-to-date list of all
  possible values.
* `:source` (a sequence of `String`s):
  The list of sources used to arrive at this portion of the SPDX expression,
  starting from the most general (the input) through to the most specific
  (the smallest subset of the input that was used to make this
  determination).

Functionality related to combing Maven POMs for license information.

In this namespace abbreviations are used for Maven's groupId, artifactId, and
version concepts.  So for example:

* `GA` means groupId & artifactId
* `GAV` means groupId, artifactId & version

In function calls where a version isn't required or provided, the library will
determine and use the latest available version, as determined from (in order):

1. your local Maven cache (usually ~/.m2/repository)
2. remote Maven artifact repositories (e.g. Maven Central, CLojars)

Other/custom Maven artifact repositories are supported via the
`set-local-maven-repo!` and `set-remote-maven-repos!` fns.

Miscellaneous functionality.
