Daru::DataFrame.from_html

Read the table data from a remote html file. Please note that this module
works only for static table elements on a HTML page, and won't work in
cases where the data is being loaded into the HTML table by Javascript.

By default - all <th> tag elements in the first proper row are considered
as the order, and all the <th> tag elements in the first column are
considered as the index.

== Arguments

* path [String] - URL of the target HTML file.
* fields [Hash] -

  +:match+ - A *String* to match and choose a particular table(s) from multiple tables of a HTML page.

  +:order+ - An *Array* which would act as the user-defined order, to override the parsed *Daru::DataFrame*.

  +:index+ - An *Array* which would act as the user-defined index, to override the parsed *Daru::DataFrame*.

  +:name+ - A *String* that manually assigns a name to the scraped *Daru::DataFrame*, for user's preference.

== Returns
An Array of +Daru::DataFrame+s, with each dataframe corresponding to a
HTML table on that webpage.

== Usage
  dfs = Daru::DataFrame.from_html("http://www.moneycontrol.com/", match: "Sun Pharma")
  dfs.count
  # => 4

  dfs.first
  #
  # => <Daru::DataFrame(5x4)>
