----------### class VimHelp
`VimHelp` can take help text of Vim via `vim` command.
#### new VimHelp([{vimBin}])
- `{vimBin}`
- Path to vim command. "vim" in the `$PATH` is used in default.#### .search({subject})
Searches `{subject}` from Vim's help and returns A Promise.
When the `{subject}` is found, the Promise will be resolved by the help text.
Otherwise, rejected an object like `{errorCode, resultText, errorText}`.
In most cases, `errorText` is useful to know the cause of error.#### .setRTPProvider({provider})
- `{provider}`
- A runtimepath provider. This is a function that has no arguments and returns an array of paths.The runtimepaths from this is used in `.search()`.
#### .helplang
An array of langs to set `'helplang'` option.
Default value is an empty array.
ex: `["ja", "en"]`### class PluginManager
PluginManager can install Vim plugins from any Git repository.
This class references the Vim plugin by `{plugin-name}`.
`{plugin-name}` is one of the following.
- A repository name of https://github.com/vim-scripts
- ex: `taglist.vim`
- A GitHub repository name like `{user}/{repos}`
- ex: `vim-jp/vital.vim`
- An URL of Git repository.
