.straight_amortization()	Calculates amortization table with straight amortization and returns a dataframe.
.annuity_amortization()	Calculates amortization table with annuity payments and returns a dataframe.
.to_html(method="annuity")	Calculates amortization dataframe (methods: 'straight' or 'annuity') and returns results to a string with html markup.
.to_json(method="annuity")	Calculates amortization dataframe (methods: 'straight' or 'annuity') and returns results to a string with JSON object.
.to_csv(path: str, method="annuity")	Calculates amortization dataframe (methods: 'straight' or 'annuity') and exports results to the .csv file.
