Custom Metrics Example

[Ishan-Kumar2]

A tutorial which shows how custom metrics can be made using Metric class would be useful.
The example can create an easy metric like the Levenshtein Distance between two strings.

Thank you for this great suggestion @Ishan-Kumar2 ! I agree this would be really helpful. If we are going to implement just one metric, perhaps, this would better be suited as a how-to guide. If we are talking about implementing more than one custom metric, we can label this as a tutorial. Would you like to work on this issue?

[Ishan-Kumar2]

Having it as a how-to-guide sounds good. I am happy to implement it once I am done with the NMT example. Till we can tag it as a help-wanted for new contributors, what do you say?

[Priyansi]

Yes sounds good! I'll also attach the hacktoberfest label.
